I'm looking at installing a single phase 240V generator. We want to have the entire building backed up by the generator. Does code require a means of disconnect between the utility and the ATS?
I'm seen several examples of installations with a mix of results.

Thanks,
Rich

The NEC prohibits ATS on the supply side of the service disconnect. See 230.80 or close to that for details

That leaves a couple of choices

Either put the ATS on the load side of the service disconnect or use a service rated ATS and that becomes the service disconnect.
